Why not? Luther died in 1546. Poor Piccolomini (who was an excellent writer, BTW) passed away in 1464. If posters on this thread can try to make hay bashing long-dead Luther, why can't I exercise my polemic skills by bringing up the various peccadilloes and crimes of the long-deceased medieval Popes? What's good for the goose...
unless for some unknown reason present day Churchmen are held responsible for this. Are they?
No, but perhaps present-day practitioners of "apologetics" -- both RC and Reformed -- should be held responsible for their one-sided histories. It's just as false and misleading to say that Galileo was burned at the stake by "the Inquisition" (da-da-DUM!), a canard which I read on a thread earlier today, as it is to pretend that Martin Luther's anti-semitism and other personal errors were unique among his contemporaries (and ancestors) both inside and outside the RC Church.
Just a question, then. How closely does modern day Lutheranism relate to Martin Luther? I honestly don’t know, and I’m honestly asking. What part of protestantism is considered current theology, has it evolved?
